By some reason I thought since the begining of the overhauling that the gearbox was in a nice condition. Thus, I didn’t reviewed it. In fact, I didn’t even emptied the oil. During the overhauling of the SV13 the time arrived to check the gearbox. I switched the power on… and the gearbox made an intense rattling noise in some speeds 🤨.
Nothing annoys more to me that a machine loosing oil and spilling it on the floor. Despite this, many machines are designed with not too much attention to this detail and lost oil mechanisms are usual. The Schaublin 13 has also some mechanisms that loose oil by design and some of them spill the oil on the floor.. ugly design I would say.
The Schaubling 13 oil level sight glass should be replaced because the original one was chipped off after pulling it out. Which materials and how to mark it?
Old mechanical sewing machines are a true gift: robust, nice, effective and useful. Refurbishing them is, however, not so easy. Screws, particulary, are most of them made following old norms or simply following no norms. This is the story of a Singer sewing machine screw.
Because of reasons, I needed to cross drill some shafts with some weird diameters. I own an old imperial Reglus drilling jig but I didn’t have the required bushings. I decided to make some of them. This post shows how drilling bushings where made.
